Social network of synapses controls their actions

A recent study suggests that synaptic plasticity is a collective action, where the behavior of one synapse influences others. The researchers found that strong competition among neighboring spines affects their dynamics and influences the direction and extent of plasticity. Understanding how neurons manage synaptic resources may contri...

Single blood test predicts 30-year cardiovascular disease risks for women

Researchers found that measuring two types of fat in the bloodstream along with C-reactive protein can predict a woman's risk for cardiovascular disease decades later.
